t's much less daunting once you've put your foot on the road to it. I'm a notorious couch potato and I don't like exercise. Half an hour of physical exercise, like jogging or fast walking a day is a start.

I'm not a big guy anyway. I'm only, what, 150 pounds? I was 190 for 'Batman,' 179 for 'Warrior.' Films make you look big.

Whatever character you play, remember they are always doing something they are not just talking.

And I like people. I like to know what you're really up to. I'm a bit of a nosey busy body. Why do they do the things they do? Why are they prepared to do the things they do to get what they want? When? Where? Who?

I'm a nice middle class public schoolboy who underachieved and wasn't going anywhere fast. I didn't get any GCSEs or A-levels. But everyone was like: "Please, will you do something?" And I was thinking: "Well, I kind of like the idea of joining the French Foreign Legion."

As actors, we have the opportunity to work with many directors. Directors only work with themselves and other actors. They never know what it is like to work with another director. So that relationship that one has with a director is entirely always the king.

Vanity is normal in performers. Does it bother other people? All the time. But nine times out of 10, that says more about them than you.
